We look at the division of 78222278 by 907 
We're looking to find how many times 907 goes into 78222278.

Going ahead to step 1:
If we divide 7 by 907, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 907

On to step 2:
907 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 907

Going ahead to step 3:
907 can be fit into 782 0 times, resulting in a remainder of 782.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 782 after subtracting 0 from 782.
Grab the next digit (2) from the dividend, add it to 782, then carry on: 7822 / 907

Advancing to step 4:
When dividing 7822 by 907, we get 8 with a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7256 away from 7822, we end up with 566.
Grab the next digit (2) from the dividend, add it to 566, then carry on: 5662 / 907

Step 5:
907 can be fit into 5662 6 times, resulting in a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 5442 from 5662, we get 220.
Append the next digit (2) from the dividend to 220 and continue with: 2202 / 907

Going ahead to step 6:
907 goes into 2202 2 times with a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 862.0
Subtracting 1814 from 2202 leaves us with 388.
Take the next digit (7) from the dividend and append it to 388, then repeat: 3887 / 907

Moving on to step 7:
907 can be fit into 3887 4 times, resulting in a remainder of 259.
Use 4 as the next digit of our solution. 
Result so far: 8624.0
Subtracting 3628 from 3887 leaves us with 259.
Grab the next digit (8) from the dividend, add it to 259, then carry on: 2598 / 907

Step 8:
When dividing 2598 by 907, we get 2 with a remainder of 784.
The next digit of our result is 2. 
Result so far: 86242.0
If we take 1814 away from 2598, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 9:
The number 907 fits into 7840 8 times, leaving a remainder of 584.
Write down 8 as next digit of the result. 
Result so far: 86242.8
If we take 7256 away from 7840, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 10:
907 goes into 5840 6 times with a remainder of 398.
Put 6 as the next digit of the answer. 
Result so far: 86242.86
If we take 5442 away from 5840, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 11:
When dividing 3980 by 907, we get 4 with a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 86242.864
Subtract 3628 from 3980 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 12:
When dividing 3520 by 907, we get 3 with a remainder of 799.
The number 3 becomes the next digit in our result. 
Result so far: 86242.8643
Subtract 2721 from 3520 to get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Step 13:
If we divide 7990 by 907, we get 8 and a remainder of 734.
The number 8 becomes the next digit in our result. 
Result so far: 86242.86438
If we subtract 7256 from 7990, we get 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Let's proceed to step 14:
907 goes into 7340 8 times with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 86242.864388
Subtract 7256 from 7340 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 86242.864388, with a leftover of 8.4e-06.
